Raid suggestion.

I know I'm not the clan leader or anything but I would like to make a suggestion regarding a builds for Fireteams during the raids. 1 Defender Titan would be absolutely mandatory as it's super move Ward of Dawn would be a valuable asset for Defensive positions. 1 Blade Dancer Hunter for clearing out multiple enemies at once. 1 Void Walker Warlock or Sunsinger Warlock (Attack Type) for zoning and increased DPS on stronger enemies with higher defense. 1 Sunsinger Warlock (Support Type) for giving buffs like faster cool down rates on grenades and melee as well as the increased amount of Orbs of Light it can produce. The last two slots can be played by any type. Do you think this a good strategy?
